For neuroblastoma, when the tumor recurs, the patient's original symptoms such as headaches, dizziness, nausea, and vomiting will reappear, occurring intermittently and worsening persistently. Most patients will experience significant increased intracranial pressure, and even frequent nausea and vomiting. Additionally, some neuroblastoma patients experience severe vertigo, especially when changing body positions, where the vertigo is particularly pronounced. For such patients, when the above symptoms and signs occur, they should go to a local hospital as soon as possible for a reassessment using cranial MRI to monitor changes in their condition.
